The latest victim of [H]ard|OCP's PSU torture chamber comes from Kingwin; the same fanless 500W Stryker model that Lee reviewed a short while ago. They were impressed with the so called overclocked mode, which allows the PSU to produce 600W and still manages not only to retain stable rails but also an efficiency rating above 89%. It soared through their torture test and managed to stay at the rated 0dB, of course. Their final verdict was very positive, though like Lee they warn that silent PSUs are more expensive and probably won't attract many buyers who can buy the same level of quality in a PSU with active cooling for significantly less money.

"Kingwin, might not be the first name that comes to mind when looking for a top-shelf PSU, but in our testing Kingwin has been very consistent with quality PSU builds. Today we look at its silent 500 watt computer power supply. We all know what happens to computer component cooling when we go silent. Can Kingwin pull off another big win?"

"Almost everyone wants the quietest yet most powerful computer possible. Most components generate noise because of the fans cooling them, or because of moving parts. Obviously, solid state drives have eliminated the necessity for moving parts for storage and liquid cooling can replace fans for most components. However, there’s still one pesky component which still generates noise: the high wattage power supply unit. Fanless PSUs have been around for a while, but they’re generally lower wattage and meant for business machines or ultra-efficient HTPCs."

Introduction and Features

Kingwin just released their first fanless power supply, the Stryker Fanless 500W, which is rated for 500W and can be easily overclocked to 600W output with only a slight drop in efficiency. That makes the Stryker STR-500 one of the highest output fanless power supplies on the market today. And the Kingwin Stryker 500W Fanless power supply is certified 80 Plus Platinum with up to 92% efficiency. High efficiency is always good but it is critical for a fanless power supply to help minimize waste heat. Combine that with a good combination of fixed and modular cables and a 5-year warranty and we have a very interesting new product to review!

Kingwin has impressed us recently with several of their new power supplies, most notably the LZP-550W that we reviewed earlier this year, which won an Editor's Choice award. In addition to the new Stryker fanless PSU, Kingwin offers a complete lineup of PC power supplies ranging across seven categories along with PC chassis, external enclosures, docking stations, cooling systems, and accessories.
